Because the CheckPaymentProcessor should extend the PaymentProcessor interface, not implement it.

Option B is the way to go, you can't have an empty method implementation, that's just wrong.

Wait, why are we using the PaymentProcessor interface? Shouldn't we just create our own class and handle the payment processing ourselves?
